Description
2 --Background of the Invention The present invention relates to exercise machines, and more particularly to machine for simultaneously exercising both arms and both legs in a natural rhythmic skiing motion, wherein the level of exercise may be controlled through frictional clutches which selectively provide resistance to arm and leg motion.
Certain devices in the prior art provide the ability to exercise with motion effects similar to the present invention, but suffer from various disadvantages which are overcome in the present invention. For example, US.
Patent No. 4,023,795, issued May 17, 1977, discloses a ski exerciser for simulating the motions required in cross country skiing. The system employs a complicated arrangement of a fly wheel with an engage able brake band and roller assemblies on either side of the fly wheel, each assembly including a one clutch, and the system operates in conjunction with cross-country skis which are mountable thereon. US. Patent 4,402,506, issued September 6, 1983 discloses a pair of dollies which are slid ably movable along two guide ways, and are adapted for standing, and in conjunction therewith the operator utilizes two poles for balance and for simulating a skiing motion. US. Patent No. 4,433,981, issued March 6, 1984 discloses a pair of slid able dollies in guide channels, in combination with a pair of simulated ski poles which also are constrained in guide channels so as to simulate the sliding motion which occurs during skinny. United Kingdom Patent Publication No. 2,007,987 discloses a pair of footrests mounted on tracks and interconnected by cords for simultaneous motion in opposite directions, and includes a hand support lever which may be connected by a link to one of the ~ootr2sts for simultaneous reciprocation therewith, which forces a motion contrary to natural body reflex motion.
2"
~22~ S
All of these patents provide a limited degree of exercise for the legs, particularly in simulation of skiing motions, and several of the patents disclose concurrent arm exercising mechanisms. However, none of patents disclose a simple device wherein the friction of resistance to motion may be carefully controlled and independently adjustable as to each arm movement, and further independently adjustable as to leg movement.
Further, none of the prior art devices are easily adaptable for transportable mounting on a single frame assembly, and for storage as a relatively flat one piece assembly.
Further, the present invention provides an exercise mechanism which requires the user to work against a constant force, which is infinitely adjustable from a free wheeling force to an irresistible force. The arm motion exerciser provides independent adjustment for exercising each arm, and requires that the arm both push and pull against a constant force. The leg exerciser provides a continuously adjustable resistance to both forward and rearward leg motion. Because of the location of the respective arm exercising levers, and the interconnecting trucks for exercising the legs, the entire apparatus provides an exercise machine which not only guides the operator through a natural motion cycle, but also provides stable supporting members to assist the operator in controlling his exercise motion. Moreover, there is no physical attachment required between the operator and the machine, and thereby the operator may readily mount and dismount from the machine without any connections to the body, and the chance of injury which might otherwise be caused by fastening devices is eliminated.
_ . . . . .
Summary of the Invention The invention includes a frame which is adapted for lying flat on a floor, the frame having at least three parallel rails for guiding a pair of wheel mounted trucks. The frame also has transverse end members, one of which has mounted thereon a pair of wheels for transporting the device.

,.. . .
In operation, the user places his fee in the cushions on top trucks 14, and grasps the hand grips 17, one in each hand. Thy feet are then moved in a back and forth sliding motion, while being constrained in the cushions of trucks 14, while at the same time handles 20 are pivoted about clutch assemblies 22. To increase or decrease the amount of work required for sliding truck 14 along the tracks, friction cable clutch 16 may be selectively loosened or tightened to provide more or less resistance to the motion ox trucks 14. Similarly, the knobs affixed to the clutch assemblies 22 may be each selectively loosened or tightened to provide more or less resistance to the movement of handles 20. In exercising with the machine as summarized above, the user finds that the friction to arm motion is constant in both directions, and does not suffer from fluctuations in resistance force depending upon handle position.
Further, the tension spring attached to at least one of the trucks 14 provides a certain degree of shock absorption which prevents an initial jerking motion which might otherwise occur when attempting to start the exercise operation.
The present invention may be embodied in other specific worms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.

,.. . .
In operation, the user places his fee in the cushions on top trucks 14, and grasps the hand grips 17, one in each hand. Thy feet are then moved in a back and forth sliding motion, while being constrained in the cushions of trucks 14, while at the same time handles 20 are pivoted about clutch assemblies 22. To increase or decrease the amount of work required for sliding truck 14 along the tracks, friction cable clutch 16 may be selectively loosened or tightened to provide more or less resistance to the motion ox trucks 14. Similarly, the knobs affixed to the clutch assemblies 22 may be each selectively loosened or tightened to provide more or less resistance to the movement of handles 20. In exercising with the machine as summarized above, the user finds that the friction to arm motion is constant in both directions, and does not suffer from fluctuations in resistance force depending upon handle position.
Further, the tension spring attached to at least one of the trucks 14 provides a certain degree of shock absorption which prevents an initial jerking motion which might otherwise occur when attempting to start the exercise operation.
The present invention may be embodied in other specific worms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
